 # HomeWizard Binding
 
 The HomeWizard binding retrieves measurements from the HomeWizard Wi-Fi P1 meter.
-The meter itself is attached to a DSMR Smart Meter and reads out the telegrams, which 
-it will forward to cloud storage. However, recently HomeWizard also added an interface 
-that can be queried locally.

+However, recently HomeWizard also added an interface that can be queried locally.
 
 This binding uses that local interface to make the measurements available.

-This should specify the IP address / host where the meter can be found.
+Note that update rate of the P1 Meter itself depends on the frequency of the telegrams it receives from the Smart Meter.
+For DSMR5 meters this is generally once per second, for older versions the frequency is much lower.
